1. Sony will begin doing something with their Gakkai purchase. Streaming games will be exclusive to Sony devices and consoles at first, with apps for other devices and PC to come later. Titles will be few in the beginning, mainly PS1/2/PSN games. They'll fold it in as part of PS+ subscriptions, with some cloud games added into the "instant game collection."
2. Sony will start making a last push for Vita, positioning it as a PS3 accessory/Wii U style controller and hinting at the function carrying over to PS4. Expect a few PSN games to have the functionality at first, with the possibility of a larger game like Last of Us patching in the functionality after release. Vita will get the Gakkai game streaming app. Price drop to $199-179, including 4GB card and game/voucher.
3. Next Xbox launches with two skus, base model with smaller storage and premium model with larger storage and pack-in games. Both models will have Kinect 2 packed-in. Kinect 2 will be able to pull off most of the crazy shit they showed back at that Kinect 1 announcement E3. They will continue their 2-year XBL subscription commitment program, bringing down the launch price of the consoles as an option for those not willing to lay down the initial $399. XBL may start aping PS+ a bit by offering a "Game of the month" for free to Gold subscribers. Expect a hype reel for the Xbox Surface tab at E3, with it to launch sometime in early 2014, emphasis on crossplay with the new Xbox and entertainment connectivity.
4. One of the console manufacturers will sign a multi-year deal with a large publisher, for a set amount of games to made permanently exclusive for their systems and devices. These will likely be only 1 or 2 AAA retail games and the rest DD/tablet games, but a big media deal will be made of it.
5. Nintendo will start bundling a pro controller or Wiimote in with the Wii U. Price drop around E3. Expect a couple of third parties to do something along the lines of "The ___ Collection," collected ports of older franchise games with nominal Gamepad functionality added, at "discount" bundle prices. Nintendo may repackage some older games in the same way.
6. PS4 will have only one sku. They will go with proprietary hard drives. They may or may not start requiring subscriptions for PSN MP access, but it will be a nominal fee in comparison to XBL ($20 a year, maybe?) and will include a "lite" version of PS+ (2-3 "free" games a year).
7. Steambox will be formally announced and shown at E3. No mention of a launch date. Don't expect to actually see it on shelves in 2013. They'll also announce Half-Life 3 and show a little footage, just to get everyone off their backs, but don't expect to see that in 2013, either.
8. At least one major AAA console game will be announced as DD only. You'll be able to buy vouchers for it in stores, but no retail disc release - unless the disc simply installs the game files and requires online activation, like PC games.
9. Amazon will begin making a bigger push into game development for tablets and PC.
10. For PS4 and Next Xbox, games with MP will mostly achieve parity with PC. BF4 having full 64-player maps, heavily filtered mod/map support, that kind of thing.
